Calculation:
Simplify the slope of the secant line
So, the slope of the secant line
Simplify the slope of the secant line
So, the slope of the secant line
Simplify the slope of the secant line
So, the slope of the secant line
Therefore, the slopes of the secant line

2009 | 18,538 |
The point
Calculation:
The slopes of the secant line
Therefore, the average rate of change in the population of the given data is 244,800.
(d)
To find: The instantaneous rate of change of population on July 1, 2009.
(d)
Answer to Problem 51RE
The instantaneous rate of change of population on July 1, 2009 is 210,000.
Explanation of Solution
Given information:
The table given below shows the population of Florida in several years:
Population of Florida | |
Year | Population(in thousands) |
2000 | 16,047 |
2002 | 16,341 |
2004 | 17,314 |
2006 | 18,019 |
2008 | 18,328 |
2009 | 18,538 |
Calculation:
The slope of the secant line from year 2009 to 2000 is 210. The average rate of change in the population of the given data is 210,000.
Therefore, the instantaneous rate of change of population on July 1, 2009 is 210,000.
(e)
To find: The estimated population of Florida in 2020.
(e)
Answer to Problem 51RE
The estimated population of Florida in 2020 is 442738.
Explanation of Solution
Given information:
The table given below shows the population of Florida in several years:
Population of Florida | |
Year | Population(in thousands) |
2000 | 16,047 |
2002 | 16,341 |
2004 | 17,314 |
2006 | 18,019 |
2008 | 18,328 |
2009 | 18,538 |
Calculation:
Consider that the population growth is liner function. The formula for a linear equation in slope-intercept form is:
The required equation is:
Substitute 2020 for x in the above equation to find the population in 2020,
Therefore, the estimated population of Florida in 2020 is 442738.
